All releases of Botan

Release Notes: A previously conditional operation in Montgomery multiplication and squaring is now always performed,
removing a possible timing channel.
A potential crash in the AES-NI implementation of the AES-192 key schedule (caused by
misaligned loads) has been fixed.
The correct flags for creating a shared library on OS X under Clang are now used,
and a
compile time incompatibility with Visual C++ 2012 has been fixed.

Release Notes: Several bugs in the TLS implementation related to session renegotiation have been fixed. The SRP password-based key agreement scheme and the Camellia block cipher have been added. Support for the Ivy Bridge hardware random number generator has also been added. Various minor bugs affecting OpenBSD and MinGW users have been fixed.

Release Notes: The SSL implementation can now be used with Visual C++ 2010's TR1 implementation. Numerous optimizations for the ECC algorithms provide 20 to 50% performance improvements. Some portability bugs affecting Solaris users were fixed, as were bugs that were triggered under the Visual C++ 2010 and Clang compilers. A bug that could cause denial of service to users verifying GOST 34.10 signatures was also fixed.

Release Notes: This release adds some new options for controlling use of Sphinx and Doxygen for generating documentation. A bug that broke runtime feature detection on x86 processors has been fixed. Support for the BeOS clone/continuation Haiku has been improved. This is the third and hopefully final release candidate for the next stable tree.

Release Notes: The documentation has been rewritten in reStructurered Text for use with the Sphinx documentation tool. The documentation has also been greatly expanded to cover new features in the latest releases.

Release Notes: A modification to the SHA-2 message expansion results in a 5% to 20% performance improvement in SHA-256 and SHA-512 on x86-64. A bug that would cause a crash on OpenBSD on SPARC has been fixed. The build system is better at configuring for ARM builds. This is the first release candidate for the next stable branch.
